UNITED STATES PATENT" OFFICE 1 Claim.

This invention relates to a block and to a wall for use in a building construction.

The general object of the invention. is to provide an improved building block from which a wall which is strong and durable can be made and wherein the units are thoroughly secured together.

Another object is to provide a building wall comprisinga plurality of blocks so arranged that the parts are interlocking in a novel manner.

Further objects and the advantages of the invention will be apparent from the following description taken in connection with the accompanying drawings, wherein:

Fig. l is a fragmentary perspective view of a Y portion of a building built with a block embodying the features of my invention;

r Fig. 2 is a top plan view of my novel block; Fig. 3 is an end elevation showingtwo of the blocks-in superimposed relation;

Fig. 4 is a central longitudinal section taken on line 4-4 of Fig. '2;

Figs. 5, 6, 7 and 8 are top plan views of blocks showing slightly modified construction but all embodying features of my invention.

Referring to the drawings by reference characters I have indicated a portion of a. building constructed of a block embodying the features of my invention'generally at l0. ;As shown this building includes outer walls II and inner walls l2 although it will be understood that other arrangements of the walls maybe made if desired without departing from the spirit of my invention.

In constructing a building according to my in- 'vention I preferably first make a foundation I3 which may be provided with longitudinally extending reenforcing members l4 and with bolts l5 embedded therein to which sillsl6 may be secured by nuts il.

The foundation is preferably of an inverted T- shape with the stem l8 directed upwardly and with my blocks indicated generally at A laid in end to end relation on the top of the foundation.

The block A is shown in detail in Figs. 2, 3 and 4 and is composed of a pair of sidemembers 20 and 2| having bevelled ends 22, 23, 24 and 25, respectively. The side members 20 and 2| are connected by a pair of webs 26 and 2'! and a second pair, 28 and 29. The width of the block equals one-half the length and the webs are spaced so that the two ends of the block are similar.

The upper faces of the side members are provided with protuberances shown as semi-cylindrical beads 30 which are interrupted as shown (Cl. 7H1) at 3| in line with the webs 26 to 29. The lower faces of the sides are provided with semi-cylin-' drical grooves 32 which are interrupted as at 33 and the construction is such that when two blocks are superimposed the beads 30 of one block 5 fit in the grooves 32 of the superimposed block. In this way the bloclm are locked against transverse and longitudinal movement relative to each other- The bevelled ends 23 and 25 on onelblock also fit the projectingends 22 and 24 on the adjacent block and thus further interlock-the blocks and prevent lateral and transverse movement thereof.

At B, Fig. 5, I indicate generally a block which is similar in all respects tothe block A except that the ends 23b and- 25b inclined have a bevel reverse to that of the ends 22b and 24b.

3 In Fig. 6 the block C is in all respects similar to the block A except that a portion of the side T member indicated at 2lc is removed to form a slot.

In Fig. 7 the block indicated generally at D is similar to the block A except that the ends 2211 and 24d are arranged at right angles to the sides of the block.

The block E indicated in Fig. 8 is a half block and'includes sides 20c and 2le whose length is equal to one-half of the sides 20 and 2| in the block A.

In building the building as shown in Fig. 1 I provide vertical bond members 40 which are provided with reenforcing members 4|. These bond membersare bonded to the block as indicated at 42 in Fig. 1 and they are also bonded to the bond beams 43 which are provided with reenforcing members 44. The rafters or floor joists 45 have securing members 46 which engage the reenforcing members 44, as clearly shown in the drawing.

The lintels 41 are made of concrete and are privided with the reenforcing members 48 which coact with the reenforcing members 49 which are embedded in concrete 50 to aflord a rigid construction.

With the block shown in Figs. 2, 5, 6, 7 and 8 all types of construction walls are provided for so that the building can be economically manufactured and will stand heavy loads and will not be seriously damaged by earthquake action.

Having thus described my invention, I claim:

A concrete block comprising an integral body having a pair of spaced parallel side members, said side members having parallel sides and having bevelled ends, the opposed ends on each side being disposed inimrallel planes, a plurality of webs connecting said side members, said webs being parallel to each other and having less thickness than the thickness of said side members, each of said side members having a plurality of longitudinal extending beads on the top thereof, said beads being semi-cylindrical in shape and having bevelled ends, said beads being interrupted in line with said webs, said beads being spaced closer to the inner face of said side members than to the outer face thereof, said side members having grooves on the bottom thereof, said grooves being semi-cylindrical in shape and having bevelled ends, said grooves being interrupted in line with said webs, said grooves being spaced closer to the inner face of said side members than to the outer face thereof, the top of said side members and the entire top of said webs and the portion between the ends of said beads being all in one plane, the bottom of said sides, the entire bottom of the webs, and the portion between the ends of the grooves being in one plane parallel to said last mentioned plane. 10
